To calculate the percentage each slice is worth, measure the angle of each slice and divide this by 360 then multiply it by 100 . To find the number of pieces of data each slice represents, multiply the percentage that each slice is worth by the total number of the data sets.

How to Convert Percents Into Angle Degrees for a Pie Graph - YouTube YouTube Start of suggested clip End of suggested clip You're going to get 180. Which means that 50% of a circle is equivalent to 180 degrees okay so whenMoreYou're going to get 180. Which means that 50% of a circle is equivalent to 180 degrees okay so when I go and draw that out. You would have your protractor.

Solution Firstly calculate the total frequency. ... Next, calculate the percentage of the total for each piece of data by dividing each one by the total frequency. ... Calculate the size of each slice of the pie chart by multiplying the 'Frequency ÷ Total Frequency' by 360 (as there are 360 degrees in one circle.)

Step 1 Convert the data to percentages. The first step is to convert the data to percentages. ... Step 2 Calculate the angle for each pie segment. A complete circle or pie chart has 360°. ... Step 3 Draw the pie chart. For this you'll need compasses and a protractor. Step 4 Add labels. The chart requires a title and labels:

Each pie chart sums up to a certain value which is equivalent to 100% or 360° based on the type of distribution (whether it is percent or degree). To find the value of certain a sector (slice): If the distribution is given in percent, simply multiply this value to the total amount of data and then divide by 100.

Pie Chart Tips, Tricks and Shortcuts : Remember that a whole circle contains 360 degrees: In a pie chart, each sector represents a certain percentage of the total data, which can be calculated using the formula: percentage of a data = (given data/total of all data) x 100.

Pie charts are used in data handling and are circular charts divided up into segments which each represent a value. Pie charts are divided into sections (or 'slices') to represent values of different sizes. For example, in this pie chart, the circle represents a whole class.
